Spectrum Sharing between UWB and Mobile in Upper 6 GHz Band

As spectrum becomes more crowded, it only makes sense to design for sharing and coexistence by default, to allow for flexibility in meeting as many deployment scenarios as possible in the most flexible manner.The upper 6 GHz band (6425-7125 MHz) has emerged as a critical frontier.While mobile operators seek this spectrum to meet escalating demands for high-capacity, low-latency applications, UWB is a radio technology that is low power and has a relatively high data transfer rate.It operates in wide bandwidths of 500 MHz (or more), currently within the range of 3.1 to 10.6 GHz, which overlaps with upper 6 GHz band.However, due to its orthogonal code characteristics, UWB user power remains below the noise floor, resulting in limited interference with mobile networks.This enables the possibility of simulating and evaluating spectrum sharing between UWB and mobile networks.Such considerations are also of fundamental importance in the application of UWB radar imaging devices poised for application in disaster risk monitoring and management.
